Parallel
Numbers 31:23
Brenton's English Septuagint · Berean Standard Bible
every thing that shall pass through the fire shall so be clean, nevertheless it shall be purified with the water of sanctification; and whatsoever will not pass through the fire shall pass through water.
everything that can withstand the fire—must be put through the fire, and it will be clean. But it must still be purified with the water of purification. And everything that cannot withstand the fire must pass through the water.
